Higher-order soliton solutions for the Sasa-Satsuma equation revisited via \(\bar{\partial }\) method. (English) Zbl 1529.35431

Summary: In optics, the Sasa-Satsuma equation can be used to model ultrashort optical pulses. In this paper higher-order soliton solutions for the Sasa-Satsuma equation with zero boundary condition at infinity are analyzed by \(\bar{\partial }\) method. The explicit determinant form of a soliton solution which corresponds to a single \(p_l\)-th order pole is given. Besides the interaction related to one simple pole and the other one double pole is considered.
